Title: Lubricant for welding metallic wire-like material and method for confirming adhesion state thereof
Inventor: TSUMURA SHUNJI
IPC: G01N21/89
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To confirm whether or not a lubricant is applied to a material surface thinly and uniformly and adheres surely, by adding a specific pts.wt. of a fluorescent substance to a dispersion solution of polytetrafluoroethylene. SOLUTION: Polytetrafluoroethylene(PTFE) is preferably one that is suspended and polymerized in methanol, halogen hydrocarbon or the like organic solvent or one that is emulsified and polymerized in water. A fluorescent substance emits clear fluorescence when ultraviolet rays of a wavelength of 320-400 nm are projected at a dark place. An addition amount of the fluorescent substance is approximately 0.0001-0.01 pts.wt. per 100 pts.wt. of the PTFE dispersion solution. When the addition amount is smaller than 0.0001 pts.wt., the adhesion is impossible to confirm. When the addition amount exceeds 0.01 pts.wt., the solvent is worsened in performance, e.g. gives rise to a blow hole, etc.  When the fluorescent substance is essentially included in the solution consisting of the PTFE emulsified and polymerized in water or suspended and polymerized in the organic solvent, the fluorescent substance is preferably one that is dissolved in the water or organic solvent, or stably dispersed.

Feed of impregnation resin is performed in the vicinity of a starting point 3 of the contactless transfer. The resin is fed to the top (one side) of the each base material 1 and kept impregnating into the base material 1 during transfer. Then the base materials 1 each are guided to a superposing roll 4 by a guide roll 2b and superposed integrally upon each other. In this instance, copper foils 5 are laminated respectively on both the top and bottom of the laminated body at a time. After lamination like this, resin curing and cutting are performed respectively by a heat treatment device 6 and cutter 7 and a laminated sheet 8 is obtained.

Inventor: YANO HIROSHI
IPC: H04R9/02
Filed: 1986-12-10
Abstract: PURPOSE:To attain a high input resistance and low-pitched sound reproduction with high quality by dividing a damper into plural parts by a straight line prolonged radially from the damper where waveform is formed radially and making the height of the wave different from adjacent divisions. CONSTITUTION:The damper is divided into 6 by a straight line prolonged radially and the height of the adjacent waves is made different. That is, the part 4b offers the amplitude with less distortion and the part 4a applies the amplitude limit. The deep wave part 4b suppresses the distortion small in setting the degree of wave deformation small even at a large amplitude near the critical amplitude. Moreover, the shallow wave part 4a applies linear elongation of wave at a constant amplitude to limit the amplitude accurately. Thus, as the entire damper, accurate amplitude limit is applied and the movement with less distortion is obtained up to the critical amplitude.
